Abstract

The present invention discloses an ice bag which can quickly drop the temperature to 26 DEG C for ice compress on wounds, fatigue refreshment and outgoing cold storage. The ice bag has the structure that a cooling agent 20 and a thin inner plastic bag 30 filled with water solution 31 are simultaneously encapsulated in an outer plastic bag 10, wherein the cooling agent is a particulate prepared from substances such as ammonium nitrate, sodium carboxymethyl cellulose, sodium chloride, etc. After the ice bag is pressed, the inner plastic bag 30 is ruptured; the water solution 31 and the cooling agent 20 are prepared; a dissolving process is a heat absorbing process so that the temperature of the ice bag is quickly dropped to 26 DEG C.

Description

A kind of ice bag

The present invention relates to a kind of ice bag, particularly a kind of under any ambient temperature, do not need via cold preservation, just can reduce to 26 ℃ rapidly, refresh oneself and the ice bag of the cold preservation of going out for wound ice compress, fatigue.

At present, traditional ice bag structure is the water of packing in a rubber bulb, leave in again treat water freezing in the refrigerating chamber of refrigerator after, take out and use and since therebetween from water to icing time-consuming long, if be badly in need of under the situation about using, certainly will be extremely inconvenient.Rubber bulb is built in the refrigerator iced if in advance water is packed into, though this method is feasible, but when use, can't determine really, therefore, can only let alone to leave unused in refrigerating chamber, take up space on the one hand, increased power consumption on the other hand, and when reality is used, because of whole rubber bulb has become solid, shaped, cause and use pillow for sleeping in extremely uncomfortable; In addition,, also be subject to the ease of solubility of ice cube, and can't carry the colleague if use when going out,

The purpose of this invention is to provide a kind of use, carry ice bag especially easily.

For reaching above-mentioned purpose, the present invention by the following technical solutions:

The present invention is made up of the inner plastic bag of coolant and a device water liquid outer plastic bag internally separated type packing; This coolant is an ammonium nitrate, sodium carboxymethyl cellulose, sodium chloride; Coolant is a graininess.

The ratio of the weight of the water liquid in above-mentioned coolant and the inner plastic bag is 1: 1.

The percentage by weight of each component is in the above-mentioned coolant: ammonium nitrate 98%, sodium carboxymethyl cellulose 1%, sodium chloride are 1%.

The present invention is that external plastic bag is exerted pressure in use, as pressing, rub with the hands or extruding, after exerting pressure, because of the inner plastic bag body is thinner, therefore, a pressurized can make inner plastic bag break, its water liquid is excessive fused with coolant, just can be at short notice, coolant is dissolved in water fully rapidly, and brings into play its chemical characteristic and then quick absorbing and cooling temperature, make ice bag under the room temperature of any environment, plunge to 26 ℃.

The invention will be further described below in conjunction with drawings and Examples:

Fig. 1 is the three-dimensional appearance sketch map of the embodiment of the invention.

Fig. 2 is the cross-sectional schematic of the embodiment of the invention.

10 is that outer plastic bag, 20 is that coolant, 30 is that inner plastic bag, 31 is water liquid.

See also Fig. 1, shown in Figure 2, the embodiment of the invention includes outer plastic bag 10, coolant 20, inner plastic bag 30, water liquid 31, be packaged with water liquid 31 in the inner plastic bag 30, be packaged with in the outer plastic bag 10 coolant 20 and in the inner plastic bag 30 of water liquid 31 is housed, the coolant 20 in the outer plastic bag 10 is 1: 1 with water liquid 31 weight ratios in the inner plastic bag 30; Wherein, coolant 20 includes ammonium nitrate, and sodium carboxymethyl cellulose, sodium chloride etc. mixes makes granular substance; The percentage by weight of the each component of coolant 20 is an ammonium nitrate 98%, sodium carboxymethyl cellulose 1%, sodium chloride 1%; Above-mentioned three kinds of components are made after the granular substance, treat 31 blendings of itself and water liquid after, have the characteristic that can absorb heat rapidly at short notice.

Water liquid 31 is the modes with the hot melt pressing, is packaged in the inner plastic bag 30 that approaches.

During making, at first with coolant 20 and the weight ratio of the inner plastic bag 30 that water liquid 31 is housed with 1: 1, pack simultaneously in outer plastic bag 10, wherein, coolant 20 in the outer plastic bag 10 can be complied with different purposes, and make the packing of various dose, but its coolant 20 must be kept 1: 1 ratio with the weight ratio of water liquid 31, to bring into play best endothermic effect.

The present invention in use, earlier outer plastic bag 10 is exerted pressure, as pressing, rub with the hands or extruding, the thin bag of inner plastic bag 30 is broken, water liquid 31 in it overflowed with coolant 20 fuse, after coolant 20 is met water, just can be dissolved in fully at short notice in the water liquid 31, its course of dissolution is the process of a heat absorption, and ice bag can be plunged to 26 ℃ under the room temperature of any environment.

Coolant 20 compositions of the present invention are a kind of organic compound, if after using, this ice bag no longer is back to be iced when utilizing once more in the refrigerator, it can be added water is diluted and is become organic fertilizer, make the nutrient supplement of plant, so, can prevent from environment is polluted.

If the present invention deposits at home when making fractional pack, when the human body collision produces lump, is used for the lump ice compress, has the effect of Repercusion analgesia; The driver uses and also can effectively remove the fatigue that is caused because of long-time driving, reaches the purpose of refreshment, and then guarantee driving safety; The student can provide pure and fresh quelling effect whenever and wherever possible after using, and improves learning efficiency; When leisure is gone out, can optionally adjust the outer package size at any time, just as a small-sized freezer, fresh-keeping to F﹠B, iced, the icebox that takes up space that carries that need not to make a great fuss is gone out, and has improved mobility greatly.

The granule characteristics of coolant of the present invention are that the finished product that ammonium nitrate, sodium carboxymethyl cellulose, sodium chloride are processed into has resistive connection or prevents that powdered rubber is because of making moist.Be heated, pressurized and become the characteristic of solid-state block, the stability that presents height, in addition, the composition of its interface activating agent has the Organic substance (organic ion) of anti-agllutination, making coolant 20 granules is water-soluble liquid 31, and another characteristic is that the particle surface of coolant 20 is coated with natural inorganic thing (mineral), can prevent that air from condensing, can effectively prevent sclerosis at its surperficial powder, improve fused degree with water; Above-mentioned substance metric density to each other is 0.670 ± 0.03 (0.64～0.70), and its oil absorbency is 11%.
